🧾 Overview
The TeraFlex Sport ST2 2.5" Suspension System is designed for Jeep Wrangler JL Unlimited owners who want a stable highway ride paired with confident trail performance. Built as a step up from basic spacer systems, the ST2 package incorporates lift coil springs, preset front lower Sport Control Arms, and progressive bump stops to optimize suspension geometry, steering feel, and overall vehicle stability.
With increased lift height over the Sport ST1, this system clears larger tires while maintaining excellent on-road manners and predictable off-road articulation. The inclusion of geometry-correcting control arms and a rear track bar bracket helps center the axles, improve roll center, and reduce body roll—making this a true street-and-trail suspension system rather than a simple lift.
✔ 2.5" suspension lift with true ST (Street & Trail) performance
✔ Front lower Sport Control Arms for improved geometry
✔ Progressive bump stops and sway bar disconnects for articulation
✔ Rear track bar bracket improves axle centering and roll control
✔ Designed for daily driving and aggressive trail use
🛠 Installation
- Bolt-on installation using factory mounting points. No cutting or welding required. Designed for straightforward installation with common tools. Professional installation and alignment are recommended to ensure optimal suspension geometry and handling.
